To provide a damping coefficient control apparatus for a shock absorber, improved so as to be capable of satisfactorily reducing longitudinal force acting on a wheel due to vertical input from a road surface, even if an equivalent inertia moment of a driving system fluctuates due to a change of a gear ratio of a transmission.SOLUTION: A damping coefficient control apparatus for a shock absorber is applied to a vehicle 20 which includes: a wheel 12 supported rotatably about a rotational axis 24 and having a tire 26; and a driving system for driving the wheel by an engine 28 as a driving source via a transmission 30. The damping coefficient control apparatus includes: a variable damping coefficient shock absorber 18 arranged between a wheel carrier and a vehicle body; and a control device 44 for controlling the shock absorber. The control device acquires information on an index indicating an equivalent inertia moment IP of the driving system, and controls a damping coefficient C of the shock absorber such that the damping coefficient C of the shock absorber becomes larger as the equivalent inertia moment indicated by the index becomes smaller.SELECTED DRAWING: Figure 1

    【課題】変速装置の変速比の変化に伴い駆動系の等価慣性モーメントが変動しても、路面からの上下入力に起因して車輪に作用する前後力を良好に低減することができるよう改良されたショックアブソーバの減衰係数制御装置を提供する。【解決手段】回転軸線24の周りに回転可能に支持されタイヤ26を有する車輪12と、駆動源としてのエンジン28により変速装置30を介して車輪を駆動する駆動系と、を備えた車両20に適用されたショックアブソーバの減衰係数制御装置であって、減衰係数制御装置は、車輪キャリアと車体との間に配設された減衰係数可変式のショックアブソーバ18と、ショックアブソーバを制御する制御装置44と、を含み、制御装置は、駆動系の等価慣性モーメントIPを示す指標の情報を取得し、指標により示される等価慣性モーメントが小さいほどショックアブソーバの減衰係数Cが大きくなるように、ショックアブソーバの減衰係数を制御する。【選択図】図1
